We already knew that Project Runway mentor Tim Gunn's new book would contain crazy stories about Anna Wintour, but he's also going after Isaac Mizrahi, Martha Stewart's daughter, Bravo, some of the Project Runway contestants, and even his own mother!

It looks like Grampa Gunn is taking the Werther's Originals out of the pockets of his cardigan and hurling them at anyone who is standing nearby.

It all comes out next week in his new book, Gunn's Golden Rules: Life's Little Lessons for Making It Work. He even told the New York Daily News that he was nicer to Mizrahi than he needed to be, "Oh, please, I was so kind to him. I mean, I wouldn't have the words to describe some of the more abhorrent behavior. He really is a terrible, terrible, terrible person." Ouch. The book also serves as a memoir and Gunn delves into his past relationships, his distant mother (who is currently deathly ill), and his homophobic father who worked for J. Edgar Hoover at the FBI. Between the dirt and the gossip, we can't wait to pick up a copy—even if we have to use it as a shield from Tim's barbs!
